SOLID--STATE RELAY BOARDS
There are four solid--state relay boards (SSR PCB3 through SSR PCB6) used on LADS. These boards (1) are
located in the main control enclosure (2). Light emitting diodes (LEDs) (3) are located next to the solid--state relays
(SSRs) (4) mounted on each board. These LEDs will turn on when a control signal is applied to the SSR and will turn
off when the control signal is removed. Knowing the status of the LED will help determine if the problem is caused by
an electronic circuit failure versus an electrical circuit failure. Table 1 provides a listing of the SSRs on each board,
showing the SSR’s position, function, input voltage, and output voltage.
